Dieren-Counting non Winningen y 4To.cllfwh'om 'itmy concern; v' i Y Beit know-n that l, MICHAEL 'CincinnatLin the .'county of Hamilton and-State of 0hio,have invented certain new and f, useful ImprovementsinDrier-Conveyers for White Lead, of which the following is a speci-,iicati'on; y y

t It is the objectof my invention to provide a drier conyey'er forwhite. lead..

-In the manufacture of white lead it is the acetic acid, or '-ot erchemicals/in suitable pots, which etrel stacked in layers one` abovevthe other withboaids and tan-bark between the layers, Iafter which thedecomposed lead .is ground by vsuiteible mills and passed through a.separator. The white lead so sepI arated is Athen ground in water,` theground .rwhite'llead-.fpbeing then vpermitted to piecipi` tetex Thelpractice heretofore has beenand still is to dry this precipitatedwhitelead in' large pans, a tedious and? time-consuming method.

l.it is thtbbject'of mymventifm t6 dispense with the drying of thiswhite lead in pans and to .provide a driei*`-co`nve ;'yery of' novelconi struction especially applicablefor this jpurf of Fig. 3

These respective end-.walls have slanting sides at their upper ends asshown at 5 which z I act as rests for top-plates or' lids 6. Theend-wall 3 has a flan 4e 7 which extends ini hwardly of the trough, inwhich there is an inlet-openingr S for the trough, an inlet-pipe 9 vcommunicating with they` opening 8.
